I used the 440 and 426 as an example. You saw neither of those against a 396 in stock eliminator. That was my point. For whatever reason, the 383s were faster than the big motors. Tirespin, quicker rev, but who knows? If you read stock eliminator history, you'll see the 343 HP 383 mopped the floor with the competition. I kinda got off on a tangent with the big motors. My mistake. In stock eliminator, you would have never seen a 440 against a 396 anyway, because it was too much of a cubic inch spread. Now, the 383s routinely wasted 409 chebbies. Pontiac anf phord were never any competition. The never had any street cred at all, IMHO. Well......phord was closer. But pontiacs were just straight up slow.
